As draft night approached, some of the heavy hitters in the NBA - Cleveland, San Antonio, Houston, Boston, the Clippers among them - were jockeying, making calls and looking for deals to try to position themselves to make a run at the Golden State juggernaut.

The Warriors' greatness has forced the rest of the league to do deep self-examination and be aggressive in upgrading their rosters if they're even going to have a chance to compete. The Celtics and Cavaliers were looking hard at Pacers star Paul George and Bulls guard Jimmy Butler, the Rockets and Spurs were looking at clearing cap space to make a run at some big-name free agents next week and the Knicks were, well, the Knicks.

Draft night always lays the groundwork for what will happen when the circus (officially known as free agency) begins on July 1. And with all of those contenders looking to make a splash, the biggest move was made by ... the Minnesota Timberwolves.

The Wolves reunited Tom Thibodeau with Butler, giving up two promising young players in Zach LaVine and Kris Dunn and the No. 7 overall pick to land one of the best two-way players in the game. The move should jumpstart Minnesota's pursuit of its first playoff spot since 2004 and, the Wolves hope, pave the way for success in free agency.

"I think it will (help) a lot," Thibodeau said. "With players, they look around the league, they see the makeup of the team, they see how they play, play together. That's the main thing. Both offensively and defensively."

The Timberwolves have long had difficulty attracting free agents to a relatively small market that spends four months of the year covered in ice and snow. Landing a top-15 player like Butler to team with Karl-Anthony Towns and Andrew Wiggins sends a sign of how aggressive the teams could be.

The Bulls plunged head-first into a rebuild with the decision, and now it's up to the Pacers to decide if they want to do the same.

Much to the dismay of Pacers GM Kevin Pritchard, George let it be known last week that he did not plan to re-sign in Indiana when he becomes a free agent next summer. Most of the league assumes that he wants to play for the Los Angeles Lakers, who appear to be in a tug-of-war with the rival Celtics for George's attention.

One of the big markets affected on Thursday night was at point guard, the deepest position in the league. Philadelphia, the Lakers, Sacramento, New York and Dallas all drafted point guards in the top 10, which could diminish the options for veterans like Jrue Holiday, George Hill, Jeff Teague and Patty Mills.

The elite point guards available - Chris Paul and Kyle Lowry - should have no trouble finding significant contracts. With Tony Parker suffering a serious injury in the playoffs, the Spurs were reportedly trying to clear space to make a run at Paul, who is widely considered the best point guard in the league. Paul has spent the last six seasons with the Los Angeles Clippers, but has yet to advance to the Western Conference finals.

The Clippers are trying to make a decision about retooling around the core of Paul, Blake Griffin and DeAndre Jordan, but really it's a decision that depends largely on Paul's thinking. He has long struggled to win big in the postseason, and heading to San Antonio to join with Kawhi Leonard or Houston to team up with James Harden could prove to be more attractive.

Lowry figures to remain in Toronto with a Raptors franchise that he has helped put back on the map, but after that there will be few teams in the market for a high-priced starting point guard. Denver, Utah, New York and Indiana could wade into those waters. But if they look at themselves as still being a couple of year away, they might be hesitant to spend big bucks on a veteran.

Other big names available include Gordon Hayward, Paul Millsap and Andre Iguodala. And while some of the very biggest names like Kevin Durant and Steph Curry figure to stay put, it only ramps up the sense of urgency for teams that have big holes to fill.

The clock is ticking and Thursday night provided the first steps toward making big improvements to the roster.

The Timberwolves rocked the boat with Butler, but the waters were calm after that, which should only mean one thing: It's about to get real choppy when the clock strikes midnight on July 1.
